How do I run a report of transactions that shows categories?

Good morning, @jegood6059-gmail.com. 

Welcome to the Community! I can provide you with some insight into our Transaction List by Vendor report in QuickBooks Online. 

After reviewing this report on my side and seeing if adding the option for categorizes was possible, there isn't a way to include this information. However, you can try different running reports and customize them to your liking. 

Submit feedback to our Product Developers to let them know how they can improve the system for you and other users. Keep up with our updates site to see what's new in the product. 

Feel free to come back with another other questions you may have about your account. Have a wonderful day!
